Numerical modelling of TEHL in bearings and gears
Advanced Lubrication - Peyman Havaej
Research description
Bearings and gears, a.o. often operate in so-called Thermo Elasto-Hydrodynamic lubrication regime (TEHL), which is characterized by small film thickness, extreme hydrodynamic pressures and local elastically deforming surfaces. To gain proper insight in the complex nonlinear lubrication phsyics of TEHL, multiphysics modelling involving Navier-Stokes equations for lubricant flow coupled to a linear elastic description for the surface deformation offers great potential for fundamental analysis. This project aims to develop and use a CFD-FSI model to investigate lubricant behaviour in smooth and rough TEHL contacts, subject to transient operating conditions.
